New Method for Production of Solar-Grade Silicon by ...

In this study, a new method for producing Si, called “halidothermic reduction”, was investigated with the purpose of producing solar-grade silicon (SOG-Si); by this method, SiCl 4 was reduced by gaseous subhalide used as the reductant. Si was produced by reacting SiCl 4 with Al subhalides, which were produced by reacting AlCl 3 with metallic Al. . Fibrous Si with diameters ranging from ...
